IMPROVEMENT IN BOOK-HOLDERS.

The Schedule referred to in these Letters Patent and making part of thesame.

Toall whom it may .concern 13e it known that I, CORELLI W. SIMPSON, ofBangor, in the county of Penobscot, and State of Maine, have invented anew andnseful or improved Book-Holder; -and l do hereby declare that thefollowing, takenin connection with the drawings which accompany and'forni part of this specication, is a description of myiinventionsutiicient to enable those lskilled inthe art'to which it appertains, toprac tise it.

rlhis invention relates to a new and useful improvement in holders toretain books open at any desired page, and is especially useful toschool-children, prevent-ing their soiling andwearing their booksv whilestudying the same. .l

The inventionconsists in a curved rigid bar, of nearly the same lengthas the width ot' the open book, to each end of which is attached aspring-clasp, formed to embrace one of the lids of the book, while tothe centre of the rod is pivoted a suitable springholder, which retainsthe book open at any desired page.

Figure l is a .perspective view of'iny invention attached to a book,shown by dotted lines; and

Figure 2 is a vertical longitudinal section, taken through the centre,and showing the joining ot' the spring-holdei to the rigid bar.

Similar letters of reference indicate corresponding parts in the severalfigures.

In the drawingsf A. represents a rigid har, of a length nearly equal tothe width of the Openbook. The .centre of this bar has an upward curveshown at a, and corresponding to the usual thickness of books. v

A raised knuckle, rl, is formed upon this central part of the rod, andthe lever b is pivoted in a trans verse slot in the knuckle, as isplainly shown in fig. 2; e being the pivot, connect-ing the two partstogether.

c is both a spring and thumb-piece, for actuating the lever b,- thisspring being secured to the lever by rivets, as shown in iig. l. v

f represents a knife, and g a fork, secured to the lever l, whichterminates in a handle, as shown.

In use, the. spring-clasps B B are attached to the respective lids' ofthe book, when, by pressing upon the thumb-piece 'or spring c, the leverb is raised, and as the spring passes the corner of the knuckle (I, itsprings the lever to a vertical position, where it remains, and'whendesired it can be closed by a reverse movement, bringing the holders fgupon the leaves, thus holding the book open until it is desired to turnto another place, when the lever isgraised and the pages turned to thedesired place.

Having thus described my invention,

What lI claim as new, and desire to secure by Letters Patent, is-

A book-holder, constructed with bar A,V springclasps B B, with theholding-device as constructed, with the lever b, spring c, and arms f y,and arranged to operatesubstantially in manner as and for the purposesspecified.
